What form do I need to sue an apartment complex for unpaid repairs?
What form do I use to sue an apartment complex for which I did roof repairs and still owes me $22,400.00? I filed a lien, but now I want to sue (pro se).
Is it legal for a contractor to require lien releases after a cutoff date?
We are a subcontractor to a contractor doing State of California Road work. The cutoff for pay estimates for Contractor is the 20th of each month. Our suppliers pre liened the job, but they modify their statement periods for us due to the 20th cutoff for Contractor's estimate period. The contractor is requiring us to provide lien releases from our suppliers using the 30th as a cutoff date. They are writing joint checks to our suppliers paying them through the 30th, but only paying us through the 20th. Is this legal?
Can the owner enforce a lien release I signed for a higher amount?
The general contractor forced me to sign a lien release that was for $407,000. I had only been paid $289,000 (inclusive of the subject payment). I performed an additional $150,000 of work after the date of the release. The owner fired the general contractor from the job. I filed a lien on the property for the $150,000. The Owner is now suing me stating that they have a lien release showing that I've been paid $407,000 and they are demanding that I remove my lien. Am I in the wrong? Do I have a case?
Can I contest a mechanics lien filed after 90 days?
A lumber yard had filed a mechanics lien against me for materials used to build a small deck costing $3400.00. This work was done May 2007 by a sub-contractor that was unlicensed . The lumber yard is claiming this was not paid. I recall receiving a preliminary notice by certified mail and asked the worker what this was he said this was a standard procedure when he purchased the materials at the lumber yard, little did I know that he used his boss' credit to purchase this material. He claims he paid his boss by cash, and his boss said that the money that he paid him was used towards a personal debt he had with him and said he did not pay money towards the material and said it was his own problem. We paid this worker by checks. The mechanics lien was filed on March 8, 2008 yet the work was finished on June 27, 2007. What should I do next; can I prove that this is an invalid lien because the lumber yard took longer than 90 days to file?
How can I contest a mechanics lien from a contractor?
I asked a contractor for a bid and told him what I was expecting for cost per sq ft. He said that was doable. The bid came back at 4 times what we discussed. I think he was deceptive and wanted to take me for what he could. How do I best fight the Mechanics Lien he put on my building?
